TSC-3® / TSC-4

TSC fused quartz is manufactured by flame fusion from refined natural quartz crystal.
The long furnace residence time guarantees a material with a low level of inclusions and bubbles, resulting in a high product yield for the quartz fabricator.

Heraeus transparent ingots are available in rectangular, round and hollow shapes and a wide range of sizes.
Ingots can be cut and ground or lapped to make blanks in a variety of shapes including rectangular or squared plates, disks and rings

Recommended use of TSC-3®

TSC-3® is ideal for viewing windows, optical components, wet bench tanks, and whenever a low alkali fused quartz material is specified.


Recommended use of TSC-4

TSC-4 is recommended when low alkali and low aluminium are specified.
